摘　　要：为了提高相控阵天线的检测效率,本文采用了相控阵天线换相测量法。通过对该测量方法建立的测量方程解的不唯一性分析,得知无论采用什么样的相位控制技术,得到测量方程系数矩阵的秩都是不满秩的,必须要利用相控阵天线一些有用的、可信的附加信息来确定真实的解。经计算机仿真验证了该方法的正确性,且证明了该测量方法不同于以往的天线测量方法,它充分利用了天线的构成特性,使测量具有极高的效率。In order to improve the test efficiency of phased array antennas, phase-shift measurement method is adopted in this paper. Through analyzing the un-unique solutions of the measurement equation established using this method, we conclude that whatever phase control technique is used, the rank of the coefficient matrix of the measurement equation is not full. Therefore it is necessary to utilize some additional useful information of the phased array antenna to determine the true solution. Computer simulation verifies the correctness of this method and proves that the proposed method is different from the existing antenna measurement methods. The method fully utilizes the composition property of the antenna under test and greatly improves the measurement efficiency.
